Title:
  using del in if clause confuses pyflakes

Status in Pyflakes:
  New

Bug description:
  code:

  ----------------------------------------
  test = True
  if False:
      del(test)
  assert(test)
  ----------------------------------------

  pyflakes complains:
  [...].py:4: undefined name 'test'

  
  i guess this may be too hard for a static analysier, in which case, how about

  ----------------------------------------
  test = True
  if False:
      del(test)
  else:
      assert(test)
  ----------------------------------------

  where the usage is in a different else branch to the del

  output:
  [...].py:5: undefined name 'test'
